Announced today is the beta release of FahCore17. It uses OpenCL so the AMD cards should show some muscle. I saw a post saying that a 7970 was doing ~47,000 ppd. They do use one cpu core so there will be some tuning to do but that goes for the NVidia cards as well.

I've never seen a gpu folding client use these many cpu cycles. This is on a GTX 670

This has been a discussion in the pre-beta comment thread (you had to have access to the file rather than just using the -beta tag) and from what I've gathered a big part of the cpu usage is related to debugging / troubleshooting code that will not be part of the public release.

So are these actually giving out points? The pre-beta testing wasn't.

I'm going to keep my fingers crossed though, not only does this core apparently bring AMD back into the fold, it also will make use of kepler GPUs. My 680 has been sitting idle while I wait for them to either come up with something that will use more than 80% of the cards power on more than just a few WUs and/or the public release of QRB for GPUs.

So, it looks like the new WUs are active on 6xxx series cards, as my backup 6950 currently in my main rig is doing about 12K ppd (more than double its usual output). However, 5xxx cards don't seem to be affected. The 5870 in my son's rig hasn't changed its PPD.

Also, the hex core in my son's rig is still pulling about 15K ppd, which is what it usually does. There obviously aren't any more cpu cycles being devoted to the video card in that rig. However, my main rig's 3570K has seen production fall from 25K to 15K. So, definitely a difference. I'll continue running the new work units on my main rig to see what they do...

Previously though I was getting about 40,000 PPD on 762X WU's. With only ~2% cpu usage per client

Hopefully the cpu usage goes down on the new units; if as you say a large part of that is debugging

Is that on your 670? Are you running any form of monitoring software (AB or Precision)? I'm wondering if the new core fully utilizes kepler cards (like the 762X WUs did) or if the power is only running around 80% (like it does for WUs writting for fermi like the 8XXX ones we've been seeing recently).
